XP501WormBase description:flp-8 encodes three copies of a
FMRFamide-related short peptide neurotransmitter;
although the FLP-8 peptide can increase pharyngeal
action potential frequency, loss of FLP-8 function does
not result in a mutant phenotype, suggesting that FLP-8
may function redundantly with other FMRFamide-like
peptides in the nervous system; FLP-8 expression is
detected in embryos and larval stages, but not in
adults; FLP-8 is expressed in the sensory neurons
ASEL/R, URXL/R, and PVM.

WormBase description:nlp-21 encodes nine predicted
neuropeptide-like proteins; in C. elegans, nlp-21 is
part of the GGARAF neuropeptide family that also
contains nlp-9; nlp-21 is expressed in a variety of
neurons, including AFD, five head neurons, the ventral
nerve cord, one anterior pharyngeal neuron, and one
tail neuron; nlp-21 expression is also detected in the
embryo and the intestine; as loss of nlp-21 activity
via large-scale RNAi screens does not result in any
obvious abnormalities, the precise role of
nlp-21-encoded peptides in development and/or behavior
is not yet known.
